"These guys are the BEST! Fast, efficient, good natured, innovative and the highest quality of craftsmanship! Project started just to fix woodshed, however it was too far gone so it came down. I saw visions of new project same time Ian did. He drew up plans the next day and I now have a woodshed and screened in back porch. I wanted them to preserve the integrity of my old house and use as much from the old woodshed as possible, barn siding, windows and church pews that came out of the house when converted from a church in 1836. So amazing! Thank you!"

Excavating questions, answered by experts

Hard soil could be a sign of overly dry dirt, either from poor drainage or drought. It's important to test the nutrient levels, density, and drainage capacity of your soil to see if it's absorbing water properly. Begin by adding a light layer of water and observing how long the soil retains moisture. If you experience a good deal of runoff, you may need to aerate your lawn, apply a wetting agent, or hire a professional for a closer look.

In most areas, you will need a permit for excavation work, even for projects that only involve grading or yard leveling. Permit requirements depend on your local government and the scope of the project, but they are especially common for significant digging or work that could affect utilities or public property. These permits help protect the local topography and prevent drainage issues. An experienced excavation company will typically know whether permits are needed and can often handle the process of pulling and closing them for you. You can also verify permit requirements by contacting your local building department and describing your project.

Slab foundations are more affordable than crawl spaces because they require minimal excavation, as the slab sits directly on the ground or on footers that only sink a few feet into the ground. Crawl spaces require excavation of the entire footprint of the home to several feet below the surface. Not only does that mean higher labor costs, but more materials are necessary for the concrete foundation walls.

A walk-behind trencher can cut through roots as long as they’re not too thick, making a project much easier than digging with a shovel and other hand tools. Assess your terrain and the number of trees in the surrounding area to determine if a walk-behind trencher will ease the job. Digging a trench by hand is much more time-consuming and labor-intensive. 

Yes. A metal detector is one of the quickest and easiest ways to find your septic tank. However, metal detectors can be too expensive (costing upward of $300 in some cases), and not everyone has a metal detector just lying around. If that’s the case for you, you can also take a long metal rod and poke it into the ground at regular intervals until you hit something—likely your septic tank lid.
